Impact driver bit Irwin PH‑2 25 mm for Phillips screws, model 1923321

Irwin impact driver bit PH‑2, 25 mm (model 1923321) is a changeable driver tip designed for Phillips screws and intended for use with impact drivers and power screwdrivers. The 25 mm length is suitable for working in confined spaces and provides a compact working profile that helps improve access and reduces the risk of cam‑out. The bit is manufactured to withstand impact loads and repeated torque application typical for fastening tasks performed with impact tools.

Advantages

The bit offers increased resistance to shock and torsional stress compared with standard screwdriver tips, which contributes to longer service life under impact driving conditions. Its precision‑formed Phillips geometry ensures secure engagement with the screw head to reduce slippage and strip damage. The short 25 mm length balances reach and control for applications where clearance is limited, while compatibility with standard 1/4" hex chucks and bit holders allows fast interchangeability during assembly or repair work.

Suitable for

• Driving Phillips (PH) screws with impact drivers and impact‑rated cordless screwdrivers
• Tight spaces and assembly tasks with limited depth or accessibility
• Construction, woodworking, cabinetry, and installation tasks requiring repetitive fastening
• Maintenance and repair operations where a durable, impact‑resistant tip is needed

Key specifications

• Tip type: Phillips PH‑2
• Length: 25 mm working length
• Shank interface: 1/4" hex compatible
• Designed for use with impact drivers and impact‑rated screwdrivers
• Material and heat treatment: impact‑resistant hardened driver steel (manufacturer specifications)

How to use

Insert the 1/4" hex shank into the compatible impact driver or bit holder until it locks in place. Align the PH‑2 tip with the Phillips screw head and apply steady, controlled pressure while operating the impact tool at the appropriate speed and torque setting for the fastener and material. Use short bursts if initial alignment is difficult, and withdraw the bit between fastenings to inspect the screw head and tip for wear. Replace the bit when tip rounding or chipping is visible to avoid screw damage.

Usage recommendations

For best performance, use this impact driver bit with tools that support impact driving and adjustable torque settings. Match screw size and type to the PH‑2 profile to minimize slippage. Store the bit in a protective case or bit holder to prevent corrosion and mechanical damage when not in use.
